BEST ANSWER:If it's a paper backed adhesive sand paper no, water will wreck the binding agents and sand paper will not stick, it will also fall apart. Personally I've not tried to use any of the sandpaper wet.

Overall I was satisfied with this product. All of the strips were nearly identical in length and provided sufficient area to work with the Deulen 12" Sharpener. I worked my way down the line and the end result was fantastic. I had a badly damaged Jointer blade and this kit enabled me to wear down both blades evenly to keep the set balanced. The only knock I have against this specific package was that the sandpaper comes with the adhesive exposed on the back. Since the product is shipped and stored with external pressure keeping them coiled up, it causes the lower grit particles to embed into the PSA layer. This leads to irregularities when trying to attach evenly to the lap plate.

All 6 strips applied in increasing order on a repurposed projector mirror.
